Researchers Cannot Find Out Why The Radius Of A Proton Is Getting Changing In Every Experiment

In 2010, researchers found a discrepancy in the size of the
proton. They took a hydrogen atom and interchanged the electron for a muon (its
heavier cousin), and found that for some unidentified reason the radius of the
proton contracted. This has been called the proton radius mystery.

The team of researchers has repeated the experiment for an
atom of deuterium, an isotope of hydrogen, and once the electron was interchanged
for the muon, the researchers detected once again a size discrepancy in the
nucleus. This discovery was described in Science.

The muon is an fundamental particle and it is about 200
times heavier than the electron. Being so heavy when, it is put into an atom
moves it much nearer to the nucleus than the electron, and its crusade can be
used to study the property of particles in the atomic nucleus.

But, the astonishing fact is that it should not change the
nucleus. Electrons and muons both have the same electric charge, which is what retains
them around the nucleus, but that does not disturb the size of the proton.

There are a few details flying around to describe this
discrepancy. One idea is that we are seeing sign of an unknown force, although
that is very doubtful.

The researchers consider the discrepancy might not be in the
different measurements, but in the old ones. The earlier measurements of the
proton and the deuteron (the nucleus of deuterium) using hydrogen spectroscopy
might not have reached the similar degree of precision.

Aldo Antognini co-author from the Paul Scherrer Institute
(PSI) in Switzerland said in a statement, “Naturally, it cannot be that the deuteron,
any more than the proton, has two different sizes.

The mystery could be solved very easily if we assume a
minimal experimental problem with the hydrogen spectroscopy."

Since the proton results, laborites around the world have
been improving their measuring devices, gaining a more precise measurement.
There has not been any verification that the discrepancy is really due to a
less accurate measurement, but the team is happy that their finding has directed
to this global upgrade.

Lead author Randolf Pohl, also from the Paul Scherrer
Institute (PSI), added, "If our value had agreed with the previous ones, there
would not have been this darned mystery of the proton radius; but there also
never would have been this worldwide surge of activity that has led to several
highly accurate measurement setups."

Confidently, new measurements will shortly be able to explain
if this is a coincidence of the experiments, or some unfamiliar physics at
work.

The Earth Watch Institute has declared the #bees as the most valuable species in the world in the last debate of the Royal Geographical Society of London.

The direct benefits that for life and #Saludhumana represent the products made by bees are secret to anyone. But the reality is that we should not stop just thinking about the benefits it brings to our health but assess its most extensive function in the natural chain that is pollination without which life on the planet would definitely be impossible. The bee is the only insect that provides food to humans. The #biodiversity is the process of interaction between living beings and the planet, the relationship between them, and of course, the biological response of the environment to the species. In this process the bee has a vital function since the world agriculture depends on 70% of these insects, said more clearly 70 of every 100 products that we use to feed depend exclusively on the bees. The balance is self-explanatory: Without po…

physicist claimed that Earth
and the entire universe could already be inside a black hole. According to the
physicist, this theory is related to the idea that the Big Bang was actually a
black hole.

As indicated in various
scientific reports, black holes can form through a number of ways such as when
a massive star bigger than the Sun collapses on itself and dies. This
occurrence causes a supernova and a formation of a black hole. Scientists also
believe that a collision between two neutron stars can create a black hole. In theory, these scenarios
indicate that black holes are formed when a massive volume of mass exists at a
certain spot in space. This causes a rift in the space-time fabric, which then
leads to a black hole, according to Express. Due to this theory, many scientists believe that
the Big Bang, which is credited as the creator of the entire universe, was
actually a black hole. According to supporters of this theory, the Big Bang was
a black hole that opened in a different …

Zoo
maintenance worker Mario spends his last moments of life with the beautiful
creatures he spent 25 years looking after. Mario has terminal cancer and his
dying wish was to spend his last moments with his favorite animals at the zoo,
the giraffes.

When
the Ambulance Wish Foundation brought Mario to the giraffe enclosure at
Rotterdam’s Diergaarde Blijdorp Zoo, nobody expected this type of reaction. The
giraffes came right over and could immediately sense something was not well
with their beloved friend. The giraffes began to nuzzle, comfort, and kiss
54-year-old Mario. It was obvious they could sense a problem.

Mario,
who has a mental disability, was also given the chance to say goodbye to his
long-time friends and colleagues at the zoo. The Ambulance Wish Foundation
relies on volunteers to make these last wishes a reality for terminally ill
people, just like Mario. Many studies have shown that animals can sense
sickness and disease in humans, including those with no visible symptoms. …

We can possibly all settle
on one thing: that technological devices are getting small in size by the day.
Now, contact lenses are getting cooler – well soon
– and all because of nanotechnology. The technology giant Sony has ramped
up their tech from something that we have only witnessed in James Bond
movies, to now being our reality.

Sony has filed for a patent that shows how their smart contact lenses will captures pictures and record videos just with a blink of an eye, keeping them in a small memory space on the lens – or on the user’s eyeballs. Not only is Sony determined
for this, but other technology giants such as Samsung and Google are also planning
for their smart contact lenses, going public with their concepts of taking
pictures, making videos and observing sugar intake; gamers will also experience
improved gaming, and other potentials are limitless. Though, Sony’s patent does
not mean we will be seeing them anytime soon. However, Sony’s release of
the lens will comprise a pi…

The high pollution in the
oceans is a big problem on the planet. According to recent research, it is
likely that in the year 2050 we will find more plastic than fish in the waters
of the seas, and for this reason there are many people working to generate solutions
to this problem, some very imaginative to reverse this situation.

Currently the novelty is a
bacterium, developed by students Jeanny Yao and Miranda Wang, who have been
developing this project since their school years and today reap the fruits of
it. They already have patents and have obtained a financing of 400 thousand
dollars to start developing the product. All this with only 20 years old. They have already won 5
prizes thanks to this project, they became popular as they were the youngest to
win the Perlman science prize. All thanks to its tiny bacteria capable of
transforming plastic into CO2 and water. The technology is used in two ways: To
clean the beaches and also to produce raw materials for clothing. “It is practical…
